(c) 260

Answer 1

Answer:

Option c is correct option

Step-by-step explanation:

SP = Rs 220

Profit % =10%

CP =

$\frac{sp \times 100}{100 + profit}$

$\frac{220 \times 100}{100 + 10} = rs \: 200$

Desired profit= 30%

SP =

$CP( \frac{100 + profit\%}{100} )$

$200( \frac{100 + 30}{100} ) = rs \: 260$
